Natto Goes Global: 'Sonomono Natto Capsules' and 'Kona Natto' Receive The Non-GMO Project Certification

Sonomono Inc. (Headquarters: Fukuoka City, Fukuoka Prefecture; Representative: Emi Hidaka) announced on May 26 that its three flagship products—'Sonomono Natto Capsules,' 'Kona Natto (Classic),' and 'Kona Natto (Mild)'—have officially received certification from 'The Non-GMO Project,' the most trusted non-GMO verification system in North America. As of May 2026, Sonomono products are the only natto products registered in The Non-GMO Project's official product database. Amidst the growing global demand for transparency, traceability, and reliable food standards, Japan's iconic fermented food, 'natto,' is entering a new era. The Non-GMO Project certification is far more rigorous than standard non-GMO labeling, requiring supply chain audits, genetic testing of raw materials, and on-site inspections. The 'Butterfly Seal' is a key benchmark for product placement in major North American natural food retailers. With this certification, Sonomono Inc. aims to accelerate its expansion into the North American market. By collaborating with the 'Kohoku Organic Research Group' in Saga Prefecture, the company has established a consistent traceability system that serves as the foundation for this international certification. Moving forward, the company plans to expand its sales channels from Amazon US to major natural food retailers, bringing Japan's traditional fermented culture to the global wellness market.
